CAR-BEARING.

SPECIFICATION forming part of Letters Patent No. 624,153, dated May 2,1899.

Application filed February 11, 1898. Serial No. 669.916. (Nomodeld Toall 1071,0171, it 771,07 concern:

Be it known that I, JACKSON R. BAKER, a citizen of the United States,residing at Jersey City, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements inCar-Bearings, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

My invention relates to certain new and useful improvements injournal-bearings for oar-axle boxes, and more particularly to the mannerof securing the disk bearing between the key and the brass, so as tohold the disk bearing loosely but permanently in its proper position.

The primary object of this invention is to secure the disk bearingwithin the, key and above the brass in such a manner that it is capableof moving freely at all times without becoming disengaged from the key,so as to accommodate itself to the variations of the brass and the axle.

A further object of the invention is to provide securing-lugs forholding the bearing in the key and means for preventing said lugsengaging the bearing tightly, so as to prevent its free action at alltimes.

My invention also has other objects in view, which will be fully andclearly pointed out in the detailed description of theinventionhereinafter in connection with the accompanying drawings, in whichFigure 1 is a longitudinal sectional view of a car-axle box embodying myinvention. Fig. 2 is a bottom plan View of the key, showing one of thelugs turned down to hold the hearing in place. Fig. 3 is a sectionalview on Fig. 4 is a detail view showing a lug riveted to the key insteadof cast integral therewith,

Referring to the drawings, in which like letters of reference denotecorresponding parts,

in all the figures, A designates a journal-box of any ordinaryconstruction adapted to receive the axle B.

It will be understood that this invention may be embodied with ajournal-box of any known construction, so far as Iain aware, and theparticular boxillu'strated in the draw- .ings is selected simply for thepurpose of showing how the invention is applied.

A brass C is arranged within the box to engage the axle in the usualmanner, and it is maintained in its proper position by means of the keyD and the concave disk bearing E. The key is of substantially the usualform, consisting of a fiat plate provided with a circular recess F toreceive the bearing. The concave disk bearin g is provided with ashoulder G on its periphery, and lugs H on the key are adapted to beturned down to engage the shoulder and hold the bearing in place in thekey. Any number of lugs may be employed, but two are sufficient, and thepreferable arrangement of these lugs is, substantially as shown in thedrawings, at opposite ends of the key. The lugs may be cast integralwith the key and bent down to hold the bearing in place, or they may bemadein the form of plates, as shown in Fig. 4, which are secured to thekey by one or more rivets I.

In order that the lug when turned down to engage the shoulder on theconcave disk bearing may not bind the shoulder in such a manner as toprevent its moving freely within the walls of the recess, I prefer tolocate the lug back a short distance from the wall of the recess, so asto provide a ledge J on the key, with which the lug will engage whenturned down. As the shoulder on the concave disk bearing does projectbelow the ledge J, it will be apparent that when the lug is turned downinto a horizontal position, as shown in Fig. 3, the end of said lug willnot bind the shoulder of the bearing tightly, but will simply have afree engagement therewith, and therefore the hearing may rotate and movefreely in the key, although to all intents and purposes permanentlysecured thereto.

Instead of making the lugs integral with the key or securing them to thekey by rivets I may cast copper lugs in the key, which can be hammereddown to hold the bearing in place and raised to permit the removal ofthe bearing for the purpose of being renewed or for any other purpose.

I am aware that changes in the form and proportion of parts anddetails-of construction of my invention may be made without departingfrom the spirit or sacrificing the advantages thereof so long as thesame embodies in its broadest sense a bearing provided with a shoulderand a key having lugs thereon to engage the shoulder and hold the key inplace, and I therefore reserve the right to make all such changes asfairly fall within the spirit and scope of the invention.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. In a car-axle box, the combination with a key, of a revolving concavedisk bearing having a shoulder thereon and lugs on said key adapted toengage the shoulder on the disk bearing to secure the said bearing inthe key, substantially as described.

2. In a ear-axle box, the combination with a key having a recesstherein, of a bearing arranged in said recess, lugs on the key to holdthe bearing in said recess and ledges to prevent the lugs binding thebearing, substantially as and for the purpose described.

3. In a car-axle box, the combination with a key having a recesstherein, a bearing arranged in said recess, a peripheral shoulder onsaid bearing, lugs on the key adapted to engage the shoulder to hold thebearing in the key and ledges located adjacent to the lugs and adaptedto prevent said lugs from binding the bearing when turned down to holdthe bearing in place, substantially as described.
